WT32-S1 WiFi/BT ModuleWiFi/BT DATASHEETWireless-Tag Technology Co.,Limitedhttp://www.wireless-tag.com-9-•GPIO0•GPIO2•MTDO•GPIO5Software can read the value of these five bits from the register "GPIO_STRAPPING".During the chip's system reset (power-on reset, RTC watchdog reset and brownout reset), the latches of thestrapping pins sample the voltage level as strapping bits of "0" or "1", and hold these bits until the chip is powereddown or shut down. The strapping bits configure the device boot mode, the operating voltage of VDD_SDIO andother system initial settings.Each strapping pin is connected with its internal pull-up/pull-down during the chip reset. Consequently, if astrapping pin is unconnected or the connected external circuit is high-impendence, the internal weak pull-up/pull-down will determine the default input level of the strapping pins.To change the strapping bit values, users can apply the external pull-down/pull-up resistances, or apply thehost MCU's GPIOs to control the voltage level of these pins when powering on ESP32.After reset, the strapping pins work as the normal functions pins.Refer to Table 3 for detailed boot modes'configuration by strapping pins.Table-3 Strapping PinsVoltage of Internal LDO (VDD_SDIO)PinDefault3.3V1.8VMTDI/GPIO12Pull-down01Booting ModePinDefaultSPI BootDownload BootGPIO0Pull-up10GPIO2Pull-downDon't-care0Debugging Log on U0TXD During BootingPinDefaultU0TXD TogglingU0TXD SilentMTDO/GPIO15Pull-up10Timing of SDIO SlavePinDefaultFalling-edge InputFalling-edge OutputFalling-edge InputRising-edge OutputRising-edge InputFalling-edge OutputRising-edge InputRising-edge OutputMTDOPull-up0011GPIO5Pull-up0101
WT32-S1 WiFi/BT ModuleWiFi/BT DATASHEETWireless-Tag Technology Co.,Limitedhttp://www.wireless-tag.com-10 -3.2 Functional Description3.2.1 CPU and Internal MemoryESP32-D0WDQ6 contains two low-power Xtensa® 32-bit LX6 microprocessors. The internal memory includes:•448 kB of ROM for booting and core functions.•520 kB (8 kB RTC FAST Memory included) of on-chip SRAM for data and instruction.•8 kB of SRAM in RTC, which is called RTC FAST Memory and can be used for data storage; it is accessedby the main CPU during RTC Boot from the Deep-sleep mode.•8 kB of SRAM in RTC, which is called RTC SLOW Memory and can be accessed by the co-processor duringthe Deep-sleep mode.•1 kbit of eFuse, of which 256 bits are used for the system (MAC address and chip configuration) and theremaining 768 bits are reserved for customer applications, including Flash-Encryption and Chip-ID.3.2.2 Low-Power ManagementWith the use of advanced power management technologies, ESP32 can switch between different powermodes.•Power modes–Active mode: The chip radio is powered on. The chip can receive, transmit, or listen.–Modem-sleep mode: The CPU is operational and the clock is configurable. The Wi-Fi/Bluetooth basebandand radio are disabled.–Light-sleep mode: The CPU is paused. The RTC memory and RTC peripherals, as well as the ULPco-processor are running. Any wake-up events (MAC, host, RTC timer, or external interrupts) will wakeup the chip.–Deep-sleep mode: Only the RTC memory and RTC peripherals are powered on. Wi-Fi and Bluetoothconnection data are stored in the RTC memory. The ULP co-processor can work.–Hibernation mode: The internal 8-MHz oscillator and ULP co-processor are disabled. The RTC recoverymemory is powered down. Only one RTC timer on the slow clock and some RTC GPIOs are active.The RTCtimer or the RTC GPIOs can wake up the chip from the Hibernation mode.•Sleep Patterns–Association sleep pattern: The power mode switches between the Active mode, Modem- andLightsleep
WT32-S1 WiFi/BT DATASHEETWireless-Tag Technology Co.,Limitedhttp://www.wireless-tag.com-11-Note:•In Modem-sleep mode, the CPU frequency changes automatically. The frequency depends on the CPUload and the peripherals used.•During Deep-sleep, when the ULP co-processor is powered on, peripherals such as GPIO and I2C areable to work.•When the system works in the ULP sensor-monitored pattern, the ULP co-processor works with theULP sensor periodically; ADC works with a duty cycle of 1%, so the power consumption is 100 μA.mode during this sleep pattern. The CPU, Wi-Fi, Bluetooth, and radio are woken up at predeterminedintervals to keep Wi-Fi/BT connections alive.–ULP sensor-monitored pattern: The main CPU is in the Deep-sleep mode. The ULP co-processor takessensor measurements and wakes up the main system, based on the data collected from sensors.Table-4 Functionalities Depending on the Power ModesPower modeActiveModem-sleepLight-sleepDeep-sleepHibernationSleep modeAssociation sleep patternULP sensor-monitored pattern-CPUONONPAUSEOFFOFFWi-Fi/BT baseband andradioONOFFOFFOFFOFFRTC memory and RTCperipheralsONONONONOFFULP co-processorONONONON /OFFOFFTable-5 Power Consumption by Power ModesPower modeDescriptionPower consumptionModem-sleepThe CPU is powered on.Max speed 240 MHz: 30 mA ~ 50 mANormal speed 80 MHz: 20 mA ~ 25 mASlow speed 2 MHz: 2 mA ~ 4 mALight-sleep-0.8 mADeep-sleepThe ULP co-processor is powered on.150μAULP sensor-monitored pattern100μA @1% dutyRTC timer + RTC memory10μAHibernationRTC timer only5μAPower offCHIP_PU is set to low level, the chipis powered off0.1μA
